SPECIFICATION forming part of Letters Patent No. 788,705, dated May 2, 1905 Application filed July 12, 1904:. Serial No 216,291.

To (r/H/ 1071,0721, if; vim/y (HI/11087711.;

Be it known that I, HELEN HARRIET COOKE, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Portable Steam-Radiators, of which the following is a specification.

My invention relates to improvements in portable steam radiators; and the object of the invention is to devise a radiator of this class whereby the heat may be applied directly underneath the radiator itself or in close proximity thereto, so that all the units of heat may be utilized to the greatest advantage, and thus fuel economized; and it consists, essentially, of a casing supported on suitable legs and provided with a hot-water receptacle at the top and a gas-heating means for such receptacle located beneath it, and a plurality of coils extending from the top of the casing to a condensing-bulb, and a pipe leading from the condensing-bulb to the water-receptacle, the parts being otherwise arranged and constructed in detail as hereinafter more particularly explained.

Figure 1 is a perspective view showing my improved individual radiator. Fig. 2 is a sec tional view showing an alternative form in which there may be several radiators attached to one heater.

In the drawings like letters of reference in dicate corresponding parts in each figure.

A is the casing, which is supported at the bottom by legs a and is provided with an areshaped diaphragm A, whereby an upper water-receptacle A is provided, and B is a water gage connected to the receptacle A".

O is a gas-burner suitably supported beneath the chamber A and is provided with a supply-pipe 0, having a tap c.

a is a tap to drain the water out oi the receptacle A D represents a series of coils extending upwardly from the casing A and communicating therewith, the coils being located adjacent to each other and each alternative one being reversely arranged. All of the coils are connected together to a slanting cross-pipe E, which is provided at one end with a condensation-bulb F, having a suitable safety-valve f. The pipe E is connected by a downwardly-extending pipe 6 to the water-receptacle, into the bottom of which it extends.

. In Fig. 2 I show the. heater separate from the radiator, the coils D of the radiator being in this case circular and extending into a bulb F, which is provided with a safety-valvef" and a condensation-diephragm f. The pipe 7" leads from the bulb down into the hollow base A. A condensation-pipe (0 leads from the center of the conical bottom of the base A to the bottom of the hot-water receptacle. The steam-supply pipe A leads from the top of the hot-water receptacle to the hollow base A, and the steam passes ofi' through the radiator-coils I), which are formed spirally in any suitable manner as may be desired and com municate at the top with the bulb F.

I am enabled by means of the bulb F to condense the steam when it gets to the top and bring it rapidly back to the hot water in the heater.

What I claim as my invention is- 1. In a portable steam-radiator, the combination with the casing and hot-water chamber and burner located beneath the same, of a coil connected with the hot-water chamber ,and a condensation-bulb communicating with the upper end of the coil and a downwardly extending pipe having its lower end communicating with the hot-water chamber and its upper end communicating with the condensation-bulb as and for the purpose specified.

2. In a steam-radiator, the combination with the casing and hot-water chamber and burner located beneath the same, of a plurality of coils arranged adjacent to each other and communicating at the bottom with the hot-water chamber, a pipe at the top into which the upper ends of the coils extend, a condensationbulb extending upwardly from the pipe and a pipe extending downwardly from the aforesaid upper pipe into the bottom of the hotwater chamber as and for the purpose specified.

3. In a steam-radiator, the combination with the casing and hot-water chamber and burner located beneath the same, of a plurality of coils arranged adjacent to each other and comdensation-bulh as and for the purpose specified.

municating at the bottom with the hot-Water chamber, a pipe at the top into which the upbulb extending upwardly from the pipe and a 5 pipe extending downwardly from the aforesaid upper pipe into the bottom of the hot- Water chamber and a safety-valve in the con- Witnesses:
